Systems for furnace weighing

Systems for furnace weighing

Our competence center offers highly accurate weighing solutions of production furnaces in metallurgical and foundry works, identification and logistics of transport crucibles, as well as the dosing and filling of powders and solids over turnkey metering systems and much more.

Innovation prize 2012

The Network Day of the Chemistry Cluster took place on September the 20th in Nurnberg. This innovation award is awarded every year. The fiwa)group presented the furnace weighing solution of the "Pre-Weight"-series and managed to reach the finals under the best 5 innovations.

FURNACE WEIGHING SOLUTION TYPE 1 – Weighbridge System

Weighing kits for total loads of 10t to 800t

Continous weighing of melting holding furnaces, in gound and tilt position

■ Individual adjustment of weighing kits to the furnace design, therefore the possibility of integrating all furnaces types (existing or new), that are built on a frame substructure (steel frame = bridge).

■ Permanent reproducibility in relation with the measurement results 0,02 – 0,5% of the product amount

■ Integrated correction system for tilting errors: no distortions of weight values by compensating influences or increase or decrease of the hydraulic oil mass

■ Constant measurement values at fluctuating operating and ambient temperature up to a maximum of 250°C (operations near the furnaces also for extruder reactors heating plants)

■ Ensuring the functionality, even at occuring high levels of dirt and dust, even when liquid metal is leaking

Continous weighing of melting holding furnaces, in gound and tilt position

A patented further development or alternative to the TYP 1 and 2 solutions

■ Individual adjustment of weighing kits to the furnace design, therefore the possibility of integrating almost all furnaces types. Ideal solution for new furnaces with raised accuracy requirements relating the measured value in all operating positions of the furnace.

■ Permanent reproducibility in relation with the measurement results from 0,03 - 0,1% of the product amount

■ Integrated correction system for tilting errors: no distortions of weight values by compensating influences or increase or decrease of the hydraulic oil mass

■ Highly mechanical stability of the load cells kits

■ Constant measurement values at fluctuating operating and ambient temperature up to a maximum of 250°C

■ Ensuring the functionality, even at occuring high levels of dirt and dust, even when liquid metal is leaking

and the hydraulic ram

FURNACE WEIGHING SOLUTION TYPE 4 – Weighing by load measuring pin

Furnace weighing by load measuring pin + plain bearings

Weighing kits for the conversion of existing furnaces, for total loads of 10t to 1.600t

Continous weighing of melting holding furnaces, in gound position

For guaranteeing stable and accurate weight measurements, the following system units have been integrated in conjunction with the load measuring pin (LMB):

Specially specified slide bearing systems between the bearing housing and the LMB result in:

■ Approval / confirmation of the correct weight values (absolute initial position of the furnace)

Load measuring pin

■ Individual adjustment of weighing kits to the furnace design, therefore the possibility of integrating almost all furnaces types (existing or new)

■ Permanent reproducibility in relation with the measurement results from 0,5 – 3% of the product amount
